Re: File access problem access(), stat()

hi,
It was a stupid error on my part.
I was declaring the function to return varchar when i was actually returning
integer. Also, i looked at varchar.c which was a great help.
It had a function that shows how to convert varchar to cstring.

Thanks tom,
vish
